I have an area for a landline telephone to sit in my kitchen that we never use anymore. This space accumulates pocket dumps and when trying to charge batteries and phones they fall off the counter from time to time. I made designed this little thing to hold up to 4 batteries or phones while they're being charged in a way they can stack vertically and won't fall off the counter. I made it to cover up the old landline phone jack using the existing cover plate hole spacing so I didn't have to put any new holes in the wall. This can be just screwed to the wall instead if you want too.
